I don’t think that an “X” in mixer model has any correlation to the gear box cover. In the KP26M1X model number for the Professional 600, the “X” designates plug type [American]. All the mixers that are numbered this way do have all metal gears and always have. [KV25GOX, KG25HOX]
The manufacturing date is a more reliable method of determining whether the gearbox cover [and thus the entire transmission] is metal. If you call KA with a serial number, they can tell you the date of manufacture.
All current, and in fact all KA mixers built since the 1940’s have direct drive transmissions with speed controlled by varying motor speed. A much more effective transmission is one with shifting gears and a constant motor speed. Unfortunately this type of shifting transmission is so costly that it is not found on home mixers. To get one, the cost of entry is about $2000 for a Hobart N50.
